Purpose : Long-term Care Insurance sets up facility standard and installation standard of aged care facilities and decides the presence of minimum number of rooms and its size in care facilities by using systematic instruments. Therefore, most aged care facilities had renovation in expansion and reconstruction following the revised regulations and even facility space structure and space composition are continuously improving. The study is to determine the purpose and trend by comparing before and after space composition of facilities which followed the implementation of Long-term Care Insurance and also to suggest hierarchical space composition suitable for aged care facilities through derived problems and to provide basic materials to plan the most appropriate facility for the aged. Methods : J-graph based on Space Syntax Theory will be schematized through in-site facility survey and before and after facility floor plan. Space composition trend will be analyzed by comparing indexes through S3 program. Results : As a result of 5 cases analysis, the following results were found; the average of whole space depth is increasing due to the Extension, the number of volunteers is decreasing and rooms for geriatric care helpers are being created due to the geriatric care helper introduction duty. Also, there are solariums being created to improve the health of the aged and dispensaries are being placed on every floor with the increase of documentary work for geriatric care helpers. With the policy implementation, care facility space composition and structure are changing with facility standard and it was analyzed that facilities were mostly put under the control of limited number of people in care room and total ground area per person. It was also found that there is increase in care space integration through before and after comparison of whole integration value. This is considered as the important result not only in facility standard satisfaction, but also in care support of geriatric care helpers and the aged, its main users. Implication : In order for elderly care facilities to have quality improvement and to develop as suitable facilities for characteristics of the aged, independent environmental facility standard preparation of elderly care facilities is needed through mutual cooperation of construction fields with regulation and policy related researches.

In asthma, T helper 2 (TH2)-type cytokines such as interleukin (IL)-4, IL-5, and IL-13 are produced by activated $CD^{4+}$ T cells. Dendritic cells played an important role in determining the fate of naive T cells into either $T_H1$ or $T_H2$ cells. We determined whether RG-II regulates the $T_H1/T_H2$ immune response by using an ovalbumin-induced murine model of asthma. RG-II reduced IL-4 production but increased interferon-gamma production, and inhibited GATA-3 gene expression. RG-II also inhibited asthmatic reactions including an increase in the number of eosinophils in bronchoalveolar lavage fluid, an increase in inflammatory cell infiltration in lung tissues, airway luminal narrowing, and airway hyperresponsiveness. This study provides evidence that RG-II plays a critical role in ameliorating the pathogenic process of asthmatic inflammation in mice. These findings provide new insights into the immunotherapeutic role of RG-II in terms of its effects in a murine model of asthma.

To elucidate alteration of purine nucleoside phosphorylase (PNP) activity of peripheral lymphocytes and helper/inducer and suppressor/cytototxic T cells in patients with thyroid tumors, the author examined PNP activity, and $CD4^+\;and\;CD8^+$ cells of peripheral blood in 20 cases of simple goiter, 9 cases of thyroid adenoma and 20 cases of thyroid cancer as well as 11 cases of adult healthy subjects as control. Diagnoses were established on the basis of commonly accepted clinical and biochemical criteria in simple goiter and were confirmed histopathologically in thyroid adenoma and cancer. All blood was obtained from veins of the patients and control subjects in Pusan National University Hospital during the period of January to August, 1991. The results obtained were summarized as follows: 1) The PNP activity was significantly decreased or tended to be decreased in thyroid adenomas and cancers as compared with control subjects and simple goiters. 2) The percentage of CD8 cells was significantly decreased or tended to be decreased in thyroid cancers as compared with simple goiters, thyroid adenomas and control subjects. 3) The CD4/CD8 ratio was significantly increased or tended to be increased in thyroid cancer as compared with simple goiters, thyroid adenomas and control subjects. On the basis of the results, it can be suggested that the immunodysfunction in thyroid cancer may be due to decreased suppressor/cytotoxic T cells, and the estimation of PNP activity of peripheral lymphocyte is a helpful test in detecting the immune status in thyroid tumors.

CSBHT is known to improve immunological response in mice and humans. In this study, CSBHT effect was examined in the context of CD4+ T cells' survival and TCR/CD3 induced activation responses. Spleen cells from 8 week BALB/c mice were cultured in CSBHT containing medium without activation for 24, 48 hr. The MTS assay and revealed that CSBHT did not stimulate spleen lymphocytes as mitogen. Spleen lymphocytes were treated with anti-CD3e/anti-CD28 antibodies for 48hr. Flow cytometry revealed that activity of T cell decreased with CSBHT concentration. CD4+ T cells were isolated and cultured ,in CSBHT containing medium for 48 hr. CSBHT did not affect survival of sorted CD4+ T cells without any involvement of APC. In order to evaluate the direct effect of CSBHT on helper T cells's proliferative capacity prior to activation, CD4+ T cells are isolated after 24hr of culture in CSBHT containing medium and activated with and without anti-CD3e/anti-CD28 activation for 48hr. A higher level of CD69 was observed in 1 ㎍/㎖ of CSBHT treatment than control using flow cytometry. But low CD69 expression was observed in 5㎍/㎖ of CSBHT treatment. Expression of mRNA for cytokines in CD4+ T cell revealed that IL-2 expression was increased in 1 ㎍/㎖. The expression of IL-2R α, INF- γ were increased with concentration. On the other hand mRNA of IL-4 was decreased in dose dependent manner. Results suggest that CSBHT may be desirable for CD4+ T cell's activity in immune responses. Further more, CSBHT may relatively activate Th1 and inactivate Th2.

Melittin is the main component of Bee Venom and has antibacterial activity against several bacteria. To produce the melittin antimicrobial peptide, we constructed transgenic silkworm that expressed melittin gene under the control BmA3 promoter using piggyBac vector. The use of the 3xP3-driven EGFP cDNA as a marker allowed us to rapidly distinguish transgenic silkworm. Mixtures of the donor vector and helper vector were micro-injected into 300 eggs of bivoltin silkworms, Baegokjam. In total, 131 larvae (G0) were hatched and allowed to develop into moths. The resulting G1 generation consisted of 36 broods, and we selected 4 broods containing at least 1 EGFP-positive embryo. The rate of successful transgenesis for the G1 broods was 11%. We identified 12 EGFP-positive G1 moths and these were backcrossed with wild-type moths. With the aim of identifying a melittin as antimicrobial peptide, we investigated the Radical diffusion Assay (RDA) and then demonstrated that melittin possesses high antibacterial activities against gramnegative bacteria.

We produced the transgenic silkworm that expressed the enhanced blue fluorescent protein (EBFP) in the cocoon of silkworms. The EBFP fusion protein, each with N- and C-terminal sequences of the fibroin H-chain, was designed to be secreted into the lumen of the posterior silk glands. The expression of the EBFP/H-chain fusion gene was regulated by the fibroin H-chain promoter. The use of the $3{\times}P3$-driven DsRed2 cDNA as a marker allowed us to rapidly distinguish transgenic silkworm. A mixture of the donor and helper vector was micro-injected into 300 eggs of silkworms, Baegokjam. We obtained 5 broods. The cocoon displayed blue fluorescence, proving that the fusion protein was present in the cocoon. Also, the presence of fusion proteins in cocoons was demonstrated by SDS-PAGE and western blot analysis. Accordingly, we suggest that the EBFP fluorescence silk will enable the production of the silk-based biomaterials.

An osmometrical method for determination of the degree of hydrolysis (DH) of hemoglobin was comparatively examined through TNBS (trinitrobenzene) sulfonic acid) method using two experimental variables $({\alpha}\;and\;{\beta})$, which were chosen based on correlation curves between hydrolysis equivalents (h) and $leucine-NH_2$ equivalents. DH values measured through osmometry and TNBS method highly correlated with $R^2$ values of $0.974{\sim}0.991$, irrespective of the reaction pHs and types of enzyme used. $DH_{osm}/DH_{TNBS}$ was >$1.438{\sim}1.656$ depending on the hydrolysis pH $7.5{\sim}10.0)$. Correlation euqations were well fit for measuring DH of Hb hydrolysate at different pH conditions. $DH_{osm}/DH_{TNBS}$ for co-treatment system using Esperase and Flavourzyme was 1.658, in good agreement with that of 1.656 for the single enzyme (Esperase) system. Thus, the osmometrical method was suggested to be a convenient, reliable, and rapid method for determination of DH of hemoglobin hydrolysates.

There has been a dramatic increase in public awareness regarding dementia during recent years. However, dementia remains a family affair and patients do not receive adequate care in Korea. This study aims to assist patients and their caregivers by establishing Home and Community based Long-Term Care in a city. The data collected for analysis include five main categories: dementia prevalence, limitations of daily activities of patients, burden of caregivers, the services that patient's family want to utilize, the resources that handle dementia in the community. Major findings can be summarized as follows: 1)The prevalence rate of dementia for elderly people is 13.1 per 100 persons. Alzheimer's disease amount to 38.9% of dementia patients and vascular dementia account for 36.7% of them 2)Eight out of ten patients have mild dementia. Almost all patients have normal ADL. IADL, however, shows different picture. In every items of IADL, about 60% of patients reveals some limitations. 3)The proportion of patients who had medical diagnosis is as low as 20%. Families of patients think dementia as normal aging process and medical doctors in the community do not give special concern to dementia patients. 4)Caregivers does not have proper social support. They suffer from long care time, experience large obstacles in respect of health, daily living, and social activity. 5)Health center and Community welfare center have launched some programs-consultation, home-visiting nursing, day care center, voluntary force mobilization and so on-for dementia patients. But they do not perform expected roles and functions because of lack of skilled personnels and inadequate coordination of relevant organizations for dementia care. 6)Families of dementia patients prefer home helper and home-visiting nurse to hospitalization. For the future, however, demand for institution-based long-term services will increase. We develope community dementia care model based on above findings as follows: 1)Health center execute community cardiovascular control program for the prevention of vascular dementia. 2)Refer to epidemiologic characteristics of patients and preference of family, the most urgent task for dementia care in this city is to expand and organize Home and Community based Long-Term Care. 3)For the continuous and comprehensive care, care plan for a patient must be prepared. Case management team should be builded to prepare this plan and coordinate relevant resources. 4)Special long-term care unit for dementia will be needed in a near future. This unit should have multiple functions, such as day-care center, short stay facility, training center for relevant personnels, besides long-term nursing home considering effective care of dementia and efficient operation of the facility. 5)Voluntary workers deserve their due efforts. Incentive mechanisms must be developed to activate voluntary activities.

In the actantial model of Algirdas Julius Greimas, a story makes 3 kinds of relationships with 6 actants, and, in these relationships, the desires of subjects and objects are operated. And, when the subject performs its desire, there are both assistance of helper and disturbance of opponent. And, the object of desire wanted by the subject is provided by sender and receiver. Using this actantial model, this study analyzed the narrative structure of the animation 'Dalbitgungjeon', and, by rearranging the subject of capacity, examined general stream of communication. Korean animations have tried to approach using archetypes of Korean culture as motifs with various perspectives. But, it is true that, compared with foreign animations dramatized using cultural archetypes, Korean animations still have something to be desired. Thus, this study analyzed the narrative structure of 'Dalbitgungjeon' which was recently producted using archetypes of Korean culture as its motif, and, rearranging the subject of capacity, examined general stream of communication. By doing this, this study tried to search for the method of producing an animation equipped with more advanced narrative structure. Of course, narrative structure of Greimas has been studied in various aspects. However, there are still not enough animation researches using cultural archetypes of Greimas. Considering such aspects, this study focused on searching for a method of using the formation of cultural archetypes based on the analysis of fables of Greimas.

Coronary intervention is now a well established method for the treatment of coronary artery disease. Coronary restenosis is one of the major limitations after coronary intervention. So medical teams advise the patients to get the follow-up coronary angiogram in 6 months after coronary intervention to know if the coronary artery stenosis recurs or not. This study was done in order to know how many patients complied with the advice, and to identify the relative factors to the compliance with getting the follow-up coronary angiogram. The subjects were 101 patients (male: 58 female: 22, mean age: $61{\pm}15$), who received coronary interventions from Jan. 1st to Mar. 31st 1997, and their data were collected from them by questionnaires one year after intervention. The questionnaires consisted of family support scale, self efficacy scale and compliance with sick role behavior scale. The result may be summarized as follows. 1. The number of patients who complied with getting the follow-up coronary angiogram were 37 people(36.6%) and did not comply with it were 64 people(63.4%). All scores of family support(t=5.56, p<.0001), self efficacy (t=4.13, p<.0001) and compliance with sick role behavior(t=5.66, p<.0001) were significantly higher in the patients who got the follow-up coronary angiogram than in those who did not get it. But there was not any relative factor in demographic variables (p>.05). 2. The major motivations for getting follow-up coronary angiogram were recurrence of subjective symptom(40.5%), the advice of medical team(32.4%), and fear of recurrence (27.1%). The restenosis rate in patients who got the follow-up coronary angiogram was 37.8%. 3. The restenosis rate was higher in the patients who had subjective symptoms than in those who did not have any subjective symptom. So subjective symptom and restenosis rate showed a high positive correlation(r=39.9, p<.001). However, 27.2% of the patients who did not have any subjective symptom showed coronary restenosis. 4. The reasons why they did not get the follow-up coronary angiogram were economic burden(37.5%), improved symptom(34.4%), busy life schedule(10.9%), fear of invasive procedure(9.4%), negative reaction of family member(3.1%), no helper for patient(3.1%) and worry about medical team's mistake (1.6%). The relative fators on compliance with getting the follow-up coronary angiogram after coronary intervention were family support, self-efficacy and Compliance with sick role behavior. And the most important reason why the patients did not get the follow-up coronary angiogram after coronary intervention was an economic burden.
